They place less electrical load on the memory controller and allow single systems to remain stable with more memory modules than they would have otherwise. Registered memory is often more expensive because of the lower volume and the additional components, so it is usually found only in applications where the need for scalability <http://en.wikipedia.org/wiki/Scalability> and stability <http://en.wikipedia.org/wiki/Robustness_%28computer_science%29> outweighs the need for a low price (servers <http://en.wikipedia.org/wiki/Server_%28computing%29>, for example). Although most server-grade memory modules are both ECC <http://en.wikipedia.org/wiki/Error_detection_and_correction#Error-correcting_code> and registered, there are both registered non-ECC modules and non-registered ECC modules."
